WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

Calibration update: Some modules are designed to be flashed or reflashed with completely new software packages. This process of reflashing the module is a calibration update.

Programmable parameters: These are options contained within the existing software. These include items such as tire size, customer preference items, and anti-theft options. The current settings are downloaded from an existing module then uploaded to a new module. They can also be configured using the diagnostic tool. Programming parameters is different from updating calibrations as no software is changed, only the options already contained in the software.

Some modules must be programmed as part of the repair procedure. If this procedure is not followed, the module does not function correctly and may set a number of diagnostic trouble codes (DTCs), including B2477 or P1639, which indicate that necessary data has not been programmed into the module.

NOTE: The vehicle must be stationary and level, with all accessories off, while configuring modules.

Modules that need programming should not be exchanged between vehicles. In most cases the parameter values or settings are unique to that vehicle, and if not set correctly, cause concerns or faults.

The diagnostic tool automatically attempts to retrieve the module configuration information from all modules and from a backup location in the powertrain control module (PCM) when vehicle ID is carried out. If the module and the PCM do not contain correct information, the diagnostic tool either requests As Built data or displays a list of items that are needed to manually configure. The diagnostic tool programs the module based on the data entered.

For additional diagnostic tool programming procedures, refer to PROGRAMMABLE MODULE INSTALLATION .

There are 3 different methods that are used for module programming:

Some modules do not support all 3 methods.
